Milestone:  Boost 1.41.0                                    |   Component:  serialization
  Version:  Boost 1.40.0                                    |    Severity:  Problem      
 Keywords:  static library dll polymorphic BOOST_DLLEXPORT  |  
------------------------------------------------------------+---------------
 If the serialization code of some polymorphic type is performed in the
 DLL, and there is a static library which derives from this type, the guid
 registration mechanism can result is duplicate guids and lead to failure.

 This issue also shows how the BOOST_DLLEXPORT (stop linker dead-stripping)
 trick results in (MSVC) linker LNK4006 warnings for this type of set up.

 The attached MSVC71 solution demonstrates the issue.
